Simple GPH addon

[mich125]

I need simple GPH addon, that will do following things:

Display Session time
Display Total gold earned
Display Gold earned per hour

There are addons with such functions, but what i need is:

This addon cant count gold deposited to guild bank as lost.

For ex:
I farmed for 1h, i earned raw gold+gold from vendoring items - 1k, spent 50g on repairs, and deposited 500g to my guild bank.

Addon cant count those 500g as gold lost. It should show in this example:

Sessiont Time: 1h
Total Gold Earned: 950g
GPH: 950g

Any idea is it even possible?
